Fig. 1 is a schematic diagram of one application scenario of a data recovery method according to some embodiments of the present disclosure.

In the application scenario of fig. 1, the electronic device 101 may first acquire incremental backup data 102 corresponding to a target virtual machine 103. Then, the resource usage 105 of the physical machine in which the target virtual machine 103 is located is detected. In the application scenario, the resource utilization 105 may be: "60%". Further, according to the resource utilization rate 105, the initial virtual machine capacity 106 of the target virtual machine 103 is adjusted to obtain a capacity-increased target virtual machine 104, wherein the capacity-increased target virtual machine 104 is enabled by restarting. As an example, the initial virtual machine capacity 106 of target virtual machine 103 may be: "memory: 1.7GB, the number of cores of a Central Processing Unit (CPU): 2 cores, size of hard disk: 250GB ". The virtual machine capacity of the target virtual machine 104 after the capacity is increased may be: "memory: 3.5GB, the core number of the central processing unit: 4 cores, size of hard disk: 500GB ". Finally, according to a pre-configured time period parameter 107, the computing resource of the target virtual machine 104 with the increased capacity is called, so as to restore the incremental data 108 to be restored in the incremental backup data 102 to the target virtual machine 104 with the increased capacity. In this application scenario, the time period parameter 107 may be: "T: 12 days 3 months-14 days 3 months ".

The electronic device 101 may be hardware or software. When the electronic device is hardware, the electronic device may be implemented as a distributed cluster formed by a plurality of servers or terminal devices, or may be implemented as a single server or a single terminal device. When the electronic device is embodied as software, it may be installed in the above-listed hardware devices. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.

It should be understood that the number of electronic devices in fig. 1 is merely illustrative. There may be any number of electronic devices, as desired for implementation.

With continued reference to fig. 2, a flow 200 of some embodiments of a data recovery method according to the present disclosure is shown. The data recovery method comprises the following steps:

step 201, obtaining incremental backup data corresponding to a target virtual machine.

In some embodiments, an execution subject (e.g., the electronic device shown in fig. 1) of the data recovery method may obtain incremental backup data corresponding to the target virtual machine in a wired connection manner or a wireless connection manner. The incremental backup data may be modification log information of the data. The incremental backup data may include at least one of: change log information of data, increase log information of data, and delete log information of data.

As an example, the incremental backup data described above may be modification log information for target data in a database (e.g., a MongoDB database) of the target distributed file store.

Step 202, detecting the resource utilization rate of the physical machine where the target virtual machine is located.

In some embodiments, the execution subject may detect a resource usage rate of a physical machine in which the target virtual machine is located. A Virtual Machine (Virtual Machine) may be a complete computer system that runs in a completely isolated environment and has complete hardware system functions through software simulation. The work that can be done in the physical machine can be implemented in the virtual machine. When creating a virtual machine in a computer, it is necessary to use a part of the hard disk and the memory capacity of a physical machine as the hard disk and the memory capacity of the virtual machine. Each virtual machine has an independent hard disk and an independent operating system, and the virtual machines can be operated like a physical machine. The resource utilization rate represents the load degree of each task executed by the current physical machine. The higher the resource utilization, the more heavily the load characterizing the physical machine to perform the various tasks. The lower the resource utilization, the less the load characterizing the physical machine performing the various tasks.

By way of example, the resource usage may be, but is not limited to, at least one of: the utilization rate of the current memory of the physical machine where the target virtual machine is located, the utilization rate of the current CPU of the physical machine where the target virtual machine is located, and the utilization rate of the current hard disk of the physical machine where the target virtual machine is located.

In some optional implementation manners of some embodiments, the detecting a resource usage rate of a physical machine in which the target virtual machine is located may include:

in the first step, in response to receiving a target operating system instruction input by a target user, popping up a popup window representing the resource use condition of each hardware of the physical machine. As an example, the target operating system instruction may be: "taskmgr".

And secondly, determining the utilization rate of the central processing unit and the internal memory of the physical machine according to the popup window. As an example, the execution subject may determine the utilization rates of the central processing unit and the memory in the physical machine by querying data analysis information at a corresponding position in the popup window.

It should be further noted that the execution agent may utilize the Linux operating system instruction to detect the resource utilization of the physical machine. The Linux operating system instruction can be a top-c command, so that process information, memory utilization rate, CPU vacancy rate and the like of a physical machine can be checked.

And 203, according to the resource utilization rate, increasing the initial virtual machine capacity of the target virtual machine to obtain the target virtual machine with increased capacity.

In some embodiments, the execution subject may upgrade, according to the resource utilization rate, an initial virtual machine capacity of the target virtual machine, to obtain the target virtual machine with an effective upgraded capacity. The virtual machine capacity may be configuration information of the virtual machine. The virtual machine capacity may include, but is not limited to, at least one of: the core number corresponding to the CPU, the size of the memory and the size of the hard disk. And the target virtual machine with the increased capacity is effective through restarting.

As an example, the execution main body may boost an initial virtual machine capacity of the target virtual machine through a desktop virtual machine software (VMware) according to a resource usage rate, so as to obtain the target virtual machine with the boosted capacity.

As an example, the execution subject may restart the capacity-boosted target virtual machine to enable the capacity-boosted target virtual machine to be effective.

And 204, calling the computing resources of the target virtual machine with the increased capacity according to a pre-configured time period parameter, so as to restore the incremental data to be restored in the incremental backup data to the target virtual machine with the increased capacity.

In some embodiments, the execution main body may call, according to a pre-configured time period parameter, a computing resource of the target virtual machine after capacity increase to restore the incremental data to be restored in the incremental backup data to the target virtual machine after capacity increase. The incremental data to be restored in the incremental backup data may be modification log information corresponding to the data to be restored. The data to be recovered may be lost data in the target database. And restoring the data to be restored to a target database in the target virtual machine through the incremental data to be restored and the latest snapshot of the physical backup. The time period parameter may be a parameter corresponding to the incremental data to be restored in the incremental backup data.

As an example, the execution subject may determine, according to a pre-configured time period parameter, incremental data to be restored from the incremental backup data. Then, the execution subject may call the computing resource of the target virtual machine with the increased capacity to restore the incremental data to be restored to the target virtual machine with the increased capacity.

In some optional implementation manners of some embodiments, in response to detecting that the incremental data to be restored is restored to the target virtual machine after the capacity is increased, the execution main body may adjust the virtual machine capacity of the target virtual machine after the capacity is increased to the initial virtual machine capacity. Here, the virtual machine capacity of the target virtual machine after the capacity is increased is adjusted to the initial virtual machine capacity, so that it is possible to avoid an influence on the performance of other tasks of the physical machine.

In some optional implementation manners of some embodiments, the execution main body may call, by using a target restoration tool, the computing resource of the target virtual machine with the increased capacity, so as to restore the incremental data to be restored in the incremental backup data to the target virtual machine with the increased capacity. As an example, the target recovery tool may include: under the MongoDB database bin catalogue, a Mongodump tool and a mongorestore tool are arranged.

Here, fig. 3 illustrates an example diagram of a physical backup data restore. From the physical backup 302, a physical backup most recent snapshot 303 is taken. The physical backup last snapshot 303 is then copied to the target virtual machine 301. Then, according to the incremental data 305 to be restored in the incremental backup data 304, the state of the data of the last snapshot 303 of the physical backup is modified, so that the data 306 to be restored can be obtained. Finally, the data to be restored 306 is restored to the target database 307.

In some optional implementation manners of some embodiments, the execution main body may modify a resource configuration item of the central processing unit and a resource configuration item of the memory corresponding to the target virtual machine to increase the core number and the memory size of the central processing unit corresponding to the target virtual machine. The above embodiments of the present disclosure have the following beneficial effects: according to the data recovery method of some embodiments of the disclosure, incremental data to be recovered in the incremental backup data can be quickly and efficiently recovered to the target virtual machine. Specifically, when the data amount of the incremental data corresponding to the target time zone is large, there are problems of a low copy speed and a low copy efficiency. Therefore, the system is down for a long time, and the user experience is poor. Based on this, the data recovery method of some embodiments of the present disclosure may first obtain incremental backup data corresponding to the target virtual machine. And then, detecting the resource utilization rate of the physical machine where the target virtual machine is located to determine the idle computing resources of the physical machine where the current target virtual machine is located. And then, according to the resource utilization rate, the initial virtual machine capacity of the target virtual machine is increased, and the target virtual machine with the increased capacity is obtained. And the target virtual machine with the increased capacity is effective through restarting. In this way, more computing resources may be subsequently used to recover the incremental data to be recovered. The data recovery speed and the copying efficiency can be greatly improved. In addition, the problem of long-time downtime is solved, and user experience is improved laterally. And finally, calling the computing resources of the target virtual machine with the increased capacity, and restoring the incremental data to be restored in the incremental backup data, corresponding to the time period, to the target virtual machine with the increased capacity. Therefore, the data recovery method can quickly and efficiently recover the incremental data to be recovered in the incremental backup data to the target virtual machine.

With further reference to fig. 4, a flow 400 of further embodiments of a data recovery method according to the present disclosure is shown. The data recovery method comprises the following steps:

step 401, obtaining incremental backup data corresponding to the target virtual machine.

Step 402, detecting the resource utilization rate of the physical machine where the target virtual machine is located.

And step 403, in response to that the resource utilization rate is less than or equal to a predetermined threshold, increasing the core number and the memory size of the central processing unit corresponding to the target virtual machine, so as to obtain the target virtual machine with increased capacity.

In some embodiments, in response to the resource utilization being less than or equal to the predetermined threshold, an execution subject (e.g., the electronic device shown in fig. 1) may increase the number of cores and the memory size of the central processing unit corresponding to the target virtual machine, so as to obtain the target virtual machine with the increased capacity.

As an example, the predetermined threshold value may be 0.8. The above resource usage rate may be 0.6. Therefore, the resource usage rate is equal to or less than a predetermined threshold. The execution main body can adjust the initial virtual machine capacity (the memory: 1.7GB, the core number of the central processing unit: 2 cores, the size of the hard disk: 250 GB) of the target virtual machine to the adjusted virtual machine capacity (the memory: 3.5GB, the core number of the central processing unit: 4 cores, the size of the hard disk: 500 GB).

As another example, in response to that the resource utilization rate is less than or equal to a predetermined threshold, the execution main body may use a desktop virtual machine (VMware) to increase the number of cores and the size of the memory of the central processing unit corresponding to the target virtual machine, so as to obtain the target virtual machine with increased capacity.

Step 404, according to a pre-configured time period parameter, invoking a computing resource of the target virtual machine with the increased capacity to restore the incremental data to be restored in the incremental backup data to the target virtual machine with the increased capacity.

In some embodiments, specific implementation of steps 401, 402, and 404 and technical effects brought by the implementation may refer to steps 201, 202, and 204 in the embodiment corresponding to fig. 2, and are not described herein again.

As can be seen from fig. 4, compared with the description of some embodiments corresponding to fig. 2, the flow 400 of the data recovery method in some embodiments corresponding to fig. 4 highlights a specific step of increasing the virtual machine capacity of the target virtual machine. Therefore, the solutions described in the embodiments can increase the number of threads of the virtual machine by increasing the number of CPU cores of the target virtual machine, and increase the running speed of the target virtual machine by increasing the size of the memory. Therefore, the speed of restoring the incremental backup data of the target virtual machine can be more clearly and simply explained.
